Why are my armpits itchy? 7 ways to get rid of itchy armpits

An itchy armpit refers to the sensation where the underarms are experiencing irritation or discomfort which can trigger the urge to scratch or rub the affected region.

Itchy armpits can be caused by a variety of reasons such as poor hygiene, excessive heat or dry skin patches. Itchiness in the underarms can be a very uncomfortable feeling, so read on to learn more about how to get rid of and prevent them.

Typically, itchy armpits are associated with itchiness or irritation in the underarm, and depending on the underlying cause, it may be mild, moderate, or severe. Several symptoms can occur alongside itchiness such as red patches under the armpits, swelling, bumps, armpit pimples, and rashes. 

Seek medical help if the itchiness persists or is accompanied by severe pain as it could indicate an infection.

1. Heat: When exposed to too much heat, your sweat glands clog up and cannot release sweat. This causes them to swell, resulting in itchy, painful bumps under your arms.

2. Poor hygiene: Keeping your underarms clean is vital to preventing itchy armpits. Underarms harbour many different kinds of bacteria. The buildup of sweat and dirt on the skin can cause these bacteria to multiply, resulting in itchy skin.

3. Razor burns or rashes: This typically occurs when an area is not shaved correctly which can lead to irritation or itchiness. If you develop a razor burn or rash, take a break from shaving for a few days and allow your skin to heal.

4. Contact dermatitis: This occurs when the skin is exposed to an irritant or an allergen, leading to redness and irritation. Such substances can include soaps, laundry detergents, or certain deodorants. If you think you’ve been exposed to an irritant, discontinue the use of all suspected products and gradually reintroduce them one by one. If no rash appears after three days, you can eliminate it as a cause. 

5. Intertrigo: This is a rash that occurs in moist areas of skin folds. It is characterised as a red or brown rash that can cause itchiness and burning sensations.

6. Sensitive skin: People with sensitive skin may be more prone to itchy armpits. The use of deodorants with harsh chemicals can cause irritation, especially to those with sensitive skin. Use gentle, fragrance-free products to prevent and get rid of itchiness.
